Caspian Sea Sediment - 16S Survey Targeted Locus (Loci)

The Caspian Sea is one of the most polluted seas in the world due to industrial and agricultural effluents as well as extraction of oil and gas reserves. Microbial communities can impact the fate of contaminants and nutrients. However, insight into the microbial ecology of the Caspian Sea significantly lags behind other marine systems. Here we describe the microbial diversity of sediments collected from three sampling stations in the Caspian Sea. This study provides a baseline assessment that may serve as a point of reference as this system changes or as remediation efforts are initiated to reduce pollution.里海（Caspian Sea）是全球受污染最为严重的海域之一，其污染源自工农业废水以及油气资源的开采活动。微生物群落可对污染物与营养盐的归趋产生重要影响。然而，当前学界对里海微生物生态学的认知，显著滞后于其他海洋生态系统。本研究对里海3个采样站点采集的沉积物的微生物多样性特征进行了详细描述。本研究提供了一项基线评估成果，可在该生态系统发生变化，或是启动污染修复工作时，作为重要的参考基准。
